SUiVIMARY

In the processing of green tea, yeast stage plays an important role and is the first factor to

decide the quality of products and affect the next stage. Research has come up with technology and

process design, equipment manufacturing is green tea with yeast yield microwave 45 - 60 kg tea

leaves / hour with yeast time 4-5 minutes, the temperature of tea blocks yeast chamber 84 ** C ± 2 "

C, relative humidity yeast tea after 59 to 61.6%, yeast thoroughly and do not depend on size, to

small tea leaves. Stabilizing equipment, monitored and controlled automatically. High quality tea

products, such as the levels of tannin, soluble substances, sugar, axitamin, are higher than the

traditional method of yeast.

Keywords: Yeast by microwave tea.
